9 Claims. (01.240 59 This invention relates to adjustable lamps designed to be used on bedsteads, although capable of general application to vertical supports such as the mirror of a bureau or other place, to'be usedas a reading lamp.

The object of the invention is to provide a novel lamp of the character above set forth which is adjustable at various angles especially adapting it for reading purposes while reclining in bed.

Another, object of the, invention is to provide a lamp composed of a few simple parts capable of lowing specification, reference being had to the accompanying drawing, wherein:

Fig. 1 is a side elevation of the adjustable lamp applied to a bedstead;

. Fig. 2 is an enlarged side elevation of the lamp, partly broken away and in section;

Fig. 3 is a top planview of Fig. 2, also partly broken away;

Fig. 4 is an enlarged section taken on line 4-4 of Fig. 2;

Fig. 5 is a vertical section taken on the line 5-5 of Fig. 3; -f

Fig. 6 is a horizontal section taken on the line 6-6 of Fig. 5;

Fig. 7 is a vertical section of a modification;

Fig. 8 is a horizontal section taken on the line 88 of Fig. 7; and

Fig. 9 is a fragmentary elevation of the bracket. 2

Referring more particularly to the drawing, l designates a bed and II a vertical support shown as the head of the bed to the back of which at the top, a bracket 12 is secured. This bracket comprises a plate or rectangular section of sheet metal secured in position by any suitable means such as screws l3 and having the intermediate part pressed outwardly, vertically to form a vertical open ended sleeve or bearing socket M which is open at the top and bottom to receive a verticalpost l for vertical adjustment therein as will be later described. The post I5 is round or cylindrical to slide vertically for vertical adjustment up or down and turn in the sleeve or socket l4 relative to the vertical support or head H for horizontal lateral adjustment in an arc. The sleeve is provided with a horizontal slot l6 ex-' tending to the flanges I411 of the bracket H. To keep the post in any desired position of vertical adjustment, it is provided with a series of spaced annular horizontal grooves IT in the periphery thereof forming shoulders. An angular key or pin l8 having a finger or handle portion l9, fits through the slot IS in the sleeve l4 and one of the grooves I! in the post 15, to hold the post in any desired position and to permit quick and easy adjustment simply by removing the pin. This adthe usual bed lamps.

justment is effected by inserting the pin or key through the slot and in 'oneof the grooves H in order that the post may be adjusted vertically and securely held in adjusted position. It should be noted that the lower end of the post is designed to extend through and'beneath the lower end of the sleeve or socket to permit the neces-' sary adjustment.

The post is provided with a horizontal forwardly extending portion or bracket arm 20 extending substantially at right angles ,to the vertical portion. and then a reduced vertically extending portion 2| forming apivot or pin bearing having a shoulder 22 formed at the bottom of the reduced portion. The opposed semi-circular ends 23 of a clamp 24 fit on the reduced "portion 2| and may be swung horizontally at any angle if desired thus giving two horizontal adjustments in arcs. The clamp comprises a pair of jaws or strips 25 of spring metal having concaved or semi-spherical sockets 26 at the opposite ends and are connected intermediately through' opposed registering apertures by a bolt 21. The semi-spherical portions 26 which are pressed out from the metal of the strips at theends opposite the semi-circular ends 23 engage a ball or spherical portion 28' for universal, movement thereon as frictionally gripped. This connection includes a reduced intermediate neck portion 29 and an adjacent flange 30 formed-with a threaded shank or end 3| adapted to be engaged by a cap nut 32 when extended through a hole in the wall 33 of a lamp shade 34. This lamp shade is shown as of the cylindrical type made of sheet metal and open longitudinally at the bottom as indicated at 35. The ends 36 of the shade are in the form of discs flanged to receive the ends of thewall 33 and one end forms a support for a lamp socket 3'! to take an electric bulb 38 and has a switch 39 axially at the outside leading to a lamp cord 40 carrying a plug 4| at its free end for insertion in a wall socket.

A lamp of the construction described is not only capable of two angular adjustments horizontally at the post or reduced bearing portion 2|, but vertical adjustment at the bracket on the vertical support or head of the bed and angular adjustment horizontally and forwardly and rearwardly on the vertical axes as well as at an inclination to either side of the universal bearing as a 'pivot axis particularly in the manner disclosed in the dotted line positions shown in Figs. 2 and 3 of the drawing. Moreover, the lamp will stay in any adjusted position and will obviate the possibility of getting loose and falling off of the support or head of the bed as is common with This is particularly true where a clamp is used to apply a lamp to a bedstead or to the vertical support such as the mirror frame of a dresser or bureau or the like which is rounded at the top. The impracticability of such lamps has been a constant annoyance to users and the difficulties encountered in connection therewith have been entirely eliminated by the present construction.

'In the form shown in Figs. 7 and 8 of the drawing, the construction is the same as heretofore described except that the sleeve bearing or socket 42 corresponding to the open ended sleeve hearing or socket I4 is closed at the bottom by turning the metal inwardly at right angles to the outpressed portion of the sheet metal as indicated at 43 to take a rod or post 44 which is supported on the bottom 43, but which is incapable of vertical adjustment except above said bottom. However, in this instance, the post has a fiat side 45 which engages the wall of the vertical support or head of the bed to prevent the post from turning instead of turning as previously described. The lamp may be very easily applied to a wooden or metal frame of a bedstead or other vertical support so as to project forwardly thereof and reflect the rays downwardly at any convenient point. However, by reason of the construction shown and described, the device is particularly adapted as a bed lamp.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

3. An adjustable lamp for bedsteads or the like comprising a plate adapted for attachment to a vertical support and having an out-pressed portion forming a vertical sleeve, a post in the sleeve and having a forwardly extending bear-r ing arm with an upwardly extending bearing, a clamp mounted on the bearing of the arm for horizontal swinging movement, a lamp shade having a detachable shank and nut with a ball and socket connection to the clamp for universal adjustment at the free end of the clamp and means to limit the turning of the post in the sleeve.

4. A lamp bracket of the classdescribed com prising a sleeve, a post mounted in the sleeve and having an arm with an upwardly extending reduced bearing portion forming a shoulder, a clamp comprising a pair of jaws having co-acting semi-circular portions at one end held on the reduced portion of the arm for swinging movement and semi-spherical bearing portions at the other end, clamping means between the jaws, a clamp and a ball member detachably clamped to the lamp and having universal bearing in the and a lamp shade universally mounted at the free end of the clamp for angular adjustment at either side or up and down.

6. An adjustable lamp comprising a socket, a post mounted in the socket and having a rigid horizontal. supporting arm with an upstanding bearing portion, a clamp frictionally mounted on the bearing portion to swing horizontally and held at any angular adjusted position and a lamp including a shade mounted on the clamp with a universal joint for horizontal turning movement and horizontal and vertical angular adjustment.
